Hi
I have a similar problem.
During instalation of windows 7 64bit edition I get pass the step with language and keyboard selection and then win7 installer fails to detect any hard drives.
I have 3 hard drives, two of them (identical) in RAID configuration connected to sata ports, other normal IDE mode conected to sata port.
Currently I have windows XP 32bit installed on my system and everything works fine. HD are not faulty. During instalation of win XP i just had to upload RAID drivers from floppy disc to get it work.
Of course I tried to upload SATA RAID drivers during instalation of windows 7, but none of the drivers I've downloaded seems to be working.
I have gigabyte GA-MA790X-DS4 motherboard with AMD SB600 chipset (that's the one controling raid I guess) and i tried to download drivers from gigabyte website. I tried those for windows vista and windows 7 64bit edition and none of them works.
After uploading drivers, win installer still fails to detect any of my hard drives.
Can anyone help?
I think the solution of both problems desribed here is finding the right driver but still i failed to do so.
